EDWARD HAMMANN, OF BROOKLYN, ASSIGNOR TO THE J. L. MOTT IRON WORKS, onNEW YORK, N. Y.

SPECIFICATION forming part of Letters -Patent No. 539,477, dated May 21,1895. Ap lication filedf'ehrnary'd, 1 894.: Serial No. 499,105.(Nomodel) To all whmn it may concern.-

Be it known that I, EDWARD HAMMANN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented an Improvement in Waterlosets, of which the following is aspecification.

In Letters Patent No. 510,598, granted to me December 12, 1893, aporcelain bowl is represented havinga flushing rim and a flange or shelfat the rear portion resting upon the inlet water way, and the seat isprovided with a seat plate resting upon the flange or shelf and securelyconnected therewith. In this closet the upper surface of the porcelainis substantially level, and any water or liquid that may be upon the topsurface of the bowl is liable to run in between the seat plate and theporcelain, and either the seat plate has to be thicker than the seat inorder to elevate the seat slightlyabove the top edge of the basin, orelse a separate filling piece of rubber or other material has to beinserted.

The present invention is primarily for preventing the risk of waterpassing along upon the nearly level surface of the bowl and passing inbetween the seat plate and the flange or shelf, and a secondary objectof the present invention is to raise the seat sufficiently above the topedge of the basin for the rubber supporting blocks that hold up the seatand allow free circulation of air, in order that the top edge of thebasin may dry off should any liquid be spilled upon the same, andanother object of the present invention is to provide for dispensingwith a wooden seat plate and for introducing in its stead a combinedplate and metal hinge. To effect these objects I make the flange orshelf with the upper surface raised above the top edge of the rim of thebowl, so that the raised surface of the shelf or ledge is level ornearly so with the under surface of the seat, and there is Sllfficientspace between the seat and the top surface of the bowl for thesupporting'blo'cks and for the passage'of air in keeping the parts dry,and this raised'shelfor flange may be more or less ornamental in itsconfiguration, and in order to dispense with the wooden seat platerepresented in my aforesaid patent, I construct the hinge in such amanner that one plate or leaf thereof rests upon the top surface of theshelf and is permanently connected therewith.

In the drawings, Figure 1 is an elevation of the closet-bowl and theseat and cover. Fig. 2 is a plan View of the lid, seat, and bowl. Fig. 3is a section of the seat and lid with a wooden seat-plate, the bowlbeing partially in section; and Fig. 4 is a plan view of the closet-bowlwith the raised flange or shelf.

Thebowl A is of any desired character and usually the same is ofporcelain and provided with a hollow flushing rim B, and the inlet waterway 0 is connected with the flushing rim, and a trap is represented atD. These parts however may be v ried according to the character of the.closet to which the present improvements are applied.

' The flange or shelf E is integral with the closet and it extends tothe rear and the outline or configuration of the same is more or lessornamental, and the top surface 2 is elevated above the top surface 3 ofthe flushing rim B, there preferably being a curve or cove between thetwo surfaces, and the surface 2 is sufficiently above the surface 3 toprevent liquid material upon the top 3 flowing upon the top surface ofthe flange or shelf E, and the under side of the seat F is usually onthe same level or nearly so as the top surface of the flange or shelf E,and it is sometimes advantageous to allow the back edge of the seat F torest upon the front part of the flange or shelf E, and the rubbersupporting blocks 4 are fastened to the under side of the seat F nearthe front part thereof and rest upon the top of the bowl A and raise theseat, so that the under surface thereof is parallel or nearly so withthe top of the bowl. These rubber blocks prevent injury to theporcelain, and there is an opening sufficiently wide between the closetand seat for the free circulation of air, so that the parts may rapidlydry should there be any water upon the top surface of the flushing rim.

The seat F may be connected to a wooden seat plate G by hinges 5, asseen in my aforesaid patent and also in Fig. 3, but in Figs. 1 and 2 ametal hinge G is represented, havingone leaf 'or plate that is adaptedto rest either directly upon the top surface 2 of the flange of shelf Eor else to rest upon a; layer of rubber or rubber washers interveningbe' tween the plate and the surface of the flange or shelf E, and thisplate extends up and is united to and forms part of the hinge 6 that isconnected to the seat F, and where a lid I is made use of, the same ishinged,preferably to the hinge pieces 6, there being a leaf 7 extendingup from the hinge pieces 6 and secured to the surface of the lid I byscrews.

The hinge may be made double as represented, the plate G having thehinge connections near its ends,or theplates of the hinges that arebolted to the shelf may be separate.

In order to connect the plate G with the flange or shelf E, bolts 8 arepreferably employed, the same passing through holes in the metal plateand in the flangeor shelf E, such bolts having suitable heads or nuts,so as to clamp the metal hinge plate firmly to the flange or shelf. Thescrews for the wooden seat plate preferably pass up from below, as seenin Fig. 3.

This improvement is very cleanly and durable and at the same timeornamental and easily kept in an acceptable condition, and in Figs. 1and 2 the edge of the flange E is represented as ornamented with amolding or bead.

I claim as my invention- 1. The porcelain closet having a shelfprojecting at the back thereof, the upper surface of the shelf beinghigher than the top edge of the closet bowl, substantially as and forthe purposes set forth.

2. The combination with the seat, of a water closet bowl having anintegral flange projecting at the back, the top surface of the flange orshelf being above the top edge of the bowl, and supporting blocksbeneath the seat 3. The combination with a water closet bowl having aflan'geor shelf projecting at one side,

the surface of which is raised above the top edge of the closet bowl, ofa seat, a metallic I hinge connected with the seat and having a plateresting upon the shelf, and means for connecting the metallic plate tothe flange or shelf, substantially as set forth.

4. The combination with the porcelain closet having a flange or shelfprojecting at one side, the surface of which is raised above the topedge of the closet bowl of a seat, and a lid and a double jointed hin'geconnecting the lid and seat and having a metallic plate extending overthe shelf, and means for connecting the metallic plate-to the porcelainflange or shelf of the closet, substantially as set forth.

5. The combination with the seat, of a water closet bowl having anintegral flange projecting at the back, the top surface of the flange orshelf being above the top edge of the bowl, and a hinge connectionbetween the shelf and seat, substantially as set forth.

6. The combination with the seat and seat plate, of a water closet bowlof porcelain having an integral flange projecting at the back, the topsurface of the flange or shelf being above the top edge of the bowl,substantially as set forth.

Signed byme this 2d day of February, 1893.
